In 1978, Enneking and Dunham⁵ classified pelvic lesion resections into 3 main types:

Enneking and Dunham Classification¹⁶

Pure Type I or  Type III resections do not require acetabular resection. Pelvic osseous integrity and strength is still maintained even though a large portion of bone may be resected.

Only with a Type II resection does the patient need consideration for limb sparing surgery or hemipelvectomy. Most of the cases discussed in this presentation have at least a Type II resection.

That being said, there is oftentimes much crossover and resections have to be classified as such. A lesion involving the pubis and the acetabulum would usually elicit Type II/III resection.
